Abstract

A mathematical model is developed and used as a basis for numerical experiments pertaining to the study of degradation of ice-containing permafrost rocks, accumulations of metastable (relict) gas hydrates, and free gas under the influence of thermal solutions and brine with account for the osmotic effect. Series of simulations with varying parameters are used to study the patterns and rates of permafrost degradation and methane release. Some of the data obtained using the model with corresponding experimental data shows good agreement.
